Application filed October 22. 1917, Serial N-o-..197T,889. Renewed November 1-1 1922. Serial No. 600,473.

1 0 all whom it may concern.

Be it known that I, LOUIS A. Casemin, a citizen of; the United States, residing at Beverly, in the county of Essex and State 5 of Massachusetts, have invented certain Improvements in Machines for Operating upon Heels, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for operating upon the heels of boots and shoes and particularly to machines for trimming the breast portion of shoe heels, for example,

Louis heels.

It has been usual to employ for this purpose a machine known as the Louis heel breast trimming machine similar to that deco scribed and claimed in United States Letters Patent No. 784,340, granted March 7,1905, on application of Benjamin F. Mayo In this machine the heel is held to a shoe support whichv engages the tread face of the heel and the bottom of the forepart of the sole.

The support is arranged for vertical movement parallel tothe plane of operation of a cutter and is raised, to cause the cutter to trim the heel, by means of a foot trcadle.

The cutter then operates from side to side of the heel to form a curved breast surface of cross groove which is straight transversely of the heel and shoe, The direction of the out upon the portion of the heel. next v.5 the shank is, therefore, tangent to the curve of, the shank and separate means ha to he provided to trim the portion of the heel to the convex curve of the shank at each side of the shank. V v

0 One object of the invention is to provide a machine which will trim the heel breast and also trim the portion next to the shank to the curve of the shank in a single operation.

' Since in theuseof the machine disclosed in the abovementioned Letters Patent the shoe is raised by manual means, it is difticult and practically impossible so to manipulate the shoe that the cutter will complete the out without breaking away or spal-ling off some of the material of the heel on the side where the cut is finished, due to the sudden ceasing of the resistance to upward movement when the cutter leaves the work. This effect is particularly notice able when heels of leatherboard are be ing treated. While this objectionable effect has been remedied in the above-mentioned foot power machine by mechanism de-' scribed and claimed in United States. Letters Patent No. 1,293,196, granted February 4;, 1919,. upon application of Daniel E. Quinlan, it is another object of this invention to provide a machine in which the support has its movement so timed and controlled by power driven means that the cutter will effeet a clean cut on the side edge where it leaves the heel.

Recently it has become "usual to breast Louis heels'with the portions we the shank convex in transverse contour. A machine for this work is disclosed and claimed in United States Letters Patent No. 1,293,134, granted February at, 1919, upon application of Thomas Lund. It is a further object of the invention to provioe an improved machine forthis purpose.

In accordance with another object of this invention, the machine is organized to perform a plurality of operations such as those mentioned, including convening the portion of the breast next the shank, trimming the side portions of the heel to the contour j of the shank, and also concaving the breast portion adjacent to the tread face all as parts of. a single operation and while the shoe is heldupon a support or carrier, where by a Louis heel breast may he completely formed in, a single operation The machine is preferably also so organized that all relative movements of the. shoe and cutters which require fatiguing effort on the part of the operator are performed by power.

A feature of the invention consists in the combination with a rotary cutter, of a shoe support between which and the cutter there r is provision for relative movement, and pow or means for moving the cutter andsupport herein, the shoe support has a to-and-fro movement and and up-and-down movement, the up-and-down movements being eflected 1 automatically in response to the to-and-fro movements. That is, as the support is moved inwardly toward the cutter and into its plane of operation, the support is auto natically raised to carry the support and shoe into the field of operation of the cutter,

and when the support is moved outwardly or away from the cutter the support is automatically lowered to its original position.

Preferably the arrangement of the cutter and the shoe on the support is such that the heel will be breasted by the cutter in a di rection from side to side of the heel to form a cross groove in the breast face. As shown herein, the automatic movement of the work support is effected at a relatively low rate so that as the cutter and heel separate at the lower side of the heel the cut is finished without breaking away or spalling off the material at the lower edge of the heel. It is desirable that the return of the work support to its original lowered or shoe receiving position shall take place quickly. Ac-

cordingly, as a feature of the invention, the

means for lowering the support is so constructed and arranged as to permit the sup-,

port to be lowered or to drop by gravity without necessarily waiting for the power means to lower it. 7

A further feature of the invention consists in a novel organization comprising a plurality of cutters, a shoe carrier, and means. for moving the carrier and cutters relatively first to effect operation of one of the cutters upon a shoe on the carrier and then to position the carrier and the other cutter for the operation of that cutter upon the shoe by relative movement of the carrier and the said cutter. As shown herein, both cutters are rotary, one cutter having convex cutting edges shaped to correspond to the I longitudinal curvature of the heel and the other cutter straight cutting edges, the latter cutter being preferably frusto-conical and arranged above the breasting cutteix The shoe support, after being positioned in the plane of operation of the convex cutter, is raised automatically for the operation of that cutter and stops opposite the upper frusto-conical cutter, the support being then movable at the will of the operator 'inwardly to cause the frusto-conical cutter to form a concave portion in the breast of the toward the'cutter for concaving a heel, and

for limiting the movement of the support toward the cutter to determine the depth oi. the concavity formed by the cutteiz, Of course, if it is not desired to perform the coucaving operation upon the heel, the inward movement may be omitted. and the support will be restored to normal position when moved outwardly while in its raised position.

Another feature of the invention'consists in means for effecting relative movement between the shoe and the breasting cutter while it is breasting the heel to cause it also to trim the portion ofthe heel breast next the shank to the transverse curve of the shank. To effect this the shoe support is arranged to permit movement thereof lengthwise of the'cutter shaft and means the direction of movement effected by the cam guide being substantially in the direction of the cutter axis. In other words, when related to the shoe in its normal posi tion sole down the cutter and shoe support are arranged for relative traverse in a direction horizontally transverse to the shoe, and means is provided for controlling the relative movement to compound with the re] ative movement of approach and separation between the cutter and the central point of the junction of the shank and heellbreast whichis normally produced by rectilinear relative traverse, a component of relative separation and approach whereby the said central point and the cutter move relatively in a curve to make convex the junction of the shank and beast A further feature of the invention consists in improved means for effecting relative movement of the shoe support and cutter to cause the breast of the heel to be given a convex shape and this means is preferably arranged to cooperate with the means for trimming the base portion of the heel or the upper forward end of the heel breast to the lateral curve of the shank so that the heel will be given avconvex breast at that portion below the shank considering the shoe in its normal position and at theportion adjacent to the shank will be trimmed to the lateral curve of the shank in the same operation.

As shown. herein the cutting edge of the cutter is of approximate V-shapev to enter the angle between the breastttace of the heel and the shank, the formed. cutting; edge swinging around into approximate perpendic'ul'arity to the cutter axis, and two cams are provided arranged substantially at right angles to each other, one producing components of movement of the shoe' perpendicular to the heel, and the other components of movement perpendicular to the shank to cause the breast, tebe curved about the vertical axis of the heel and about the longitudinal axis of the shoe or curved horizontally transverse to the shoe considering the shoe in its normal position sole down.

- A further feature of the invention consists in novel positioning means for determining the lateral position of the torepart of the shoe upon the shoe support.

Another feature of the invention consists in novel clamping means for the shoe heel which not only effectively holds the heel :trom lateral movement during the opera tion of the first cutter, but positions the shoe heel centrally ot the Second cutter to receive the concaving cut on the portion of the breast near the top lift. The clamping means is arranged to engage the heel on opposite sides and is adapted to be operated by one of the operators hands while he holds the shoe with both hands upon the support or carrier. I 7

These and other features of the invention will appear more fully from the following detailed description when read in connection with the. accompanying drawings and will be pointed out in the appended claims.

'teterring to Fig. 1 of the drawings, the numeral 2 indicates the column of the machine in which are bearings for a shafts]; carrying tight and loose pulleys 6, 8, re-

spectively, for the application of power to the machine. The shaft 4t carries two other pulleys l0, 12,.the smaller of which is belted to. a suction fan 14;. for drawing chips and dust away from rotary cutters 16, 18 which are driven from the other pulley 12.. On the cutter shafts 20, 22 are pulleys 2 L, 26. A belt 28 connects the pulley 24 to the pulley 12 in the usual manner. and another belt 3'O'is arranged outside of the belt 28 on the pulley 12 and extends over the pulley 26 to drive the rotary cutter 18. I

The work support or carrier includes mechanism for assisting the operator in positioning and holding the work in proper orientation for the operation of the cutters which will now be described with reference to Figs. 2, 5, 6 and 7. The tread "face of: the heel is rested against a plate 40 which is normally below both of thecutters (Fig. 2'). The t'orepart of the sole rests against a cylindrical spindle e2 which is mounted for rotation on a bracket 50. On the spindle aretwo series of pins 44, 46 spirally arranged, the pins of one series being opposite the corresponding pins of the other series The first pin of one series is arranged nearest to the first pin of the other series and thesecond pin of one series a. little farther distant from the corresponding pin of the other series and so on, so that by rotating the spindle a pair of pins may be selected suitably spaced to admit between them the sole of a shoe ot' the width to be operated upon by the machine. In .F 2 the pair. of pins which is nearest together is shown. in position to receive between them the sole of a shoe, the tread face of the heel of which is rested upon the plate 410. At the base of the spindle 42 is a bevel collar 48 having successive numbers co-operating with an index mark on the bracket 50 to indicate the proper setting of the spindle and. pins for shoe soles oi" iliflerent widths, the spindle being held in a split clamp in the bracket Bibby a cap screw The position of the shoe longitudinally oil. the

cutter shaft is controlled by a plate havof lever-s68, 70 pivoted between-their ends on )ins 72 7% sunorted on a member '4' 6. r i 7 n The pairs or levers 68, 40' on the r ends opposite the clamps 60, 62 havei-nclined faces which are engaged by co-operating faces 78, 7 9 (Figs. 6 and 7). formed on a Ushaped member 80 pivoted at 82 to the support 76'. Obviously, movement of the member Soto of the shoe.

' clamps 64, 66 are on levers 84, 86'mounted on the pivots 72, 74: and having their rear ends engaged by the ends of levers 88, 90 which have their ends connected by an integral sleeve portion 91 which is also pivoted on the pin 82. The levers 88, 90 are actuated by springs 92, 94: connecting them to the U-shaped member 80. It will be seen that the movement of the member 80 toward the heel will also actuate the levers 88, 90 through the springs 92, 94, causing them to separate the outer ends of the levers 84, 86 and move the clamps 64, 66 toward the heel and clamp it at points on its opposite sides near the seat face of the heel. The clamps 60, 62 are actuated directly and posi tively by the member 80 and the clamps 64, 66 are actuated yieldingly through the springs 92, 94. Each of the clamp levers is provided with an opening spring located in a slot 71 of the lever and acting on the pivot of the lever to swing the clamp open when permitted to do so by its closing mechanism.

This U-shaped member 80 is arranged to be operated by pressure of the operators right handiupon a handle portion 81, as indicated in Figs. 5 and 6. The support 76 upon which the clamps are mounted has T-guide 93 which engages a T-slot 41 in the plate (shown in Fig. 1 where the support 76 is removed) and permits movement of the support 76 relatively to the plate 410 longitudinally of the shoe. A screw 95 (Figs. 5 and 6) has a collar 96 engaging a recess in the plate 10 to hold the screw from longitudinal movement and has threaded engagement with the support 76 so that by rotationof a thumb head 98 on the screw the support 76 and the clamping means which it carries may be conveniently adjusted longitudinally of the shoe. The rear facev of the heel restsagainst a surface 75 (Figs. 2 and 6) on the member 76 which constltutes an abut-V ment to determine the longitudinal position This abutment is, of course, adjustable by the thumb head 98 to determine the amount of material to be removed from the heel by the cutter.-

The plate 40 forms part of a member 100 which carries the bracket 50. The member 100 (Fig. 1) has a cylindrical portion 101 fitted in a split clamp in the upper end of a post 102. The split clamp is tightened by a screw 104. Conveniently to adjust the member 100 vertically when the clamp is loosened, a screw 106 is provided which is threaded into clamp nut in the post 102 formed, as shown, for that purpose.

and has a capstan head 107 bearing against a lower face of the member 100. The. 0st 102 is pivoted at 110 at its lower end ig. 4c) for swinging movement to carry the work supporting and positioning devices toward and from the machine in a direction somewhat inclined to the cutter shafts-20, 22. The extent of this movement is determined by a slot 111 in an arm 112 fastened at 11 to the machine frame. The pivot 110 extends through a block 115 which is pivoted by a stem 117 to the end of a lever 119. The stem 117 permits lateral play of the post 102 in the slot 111. This mounting, however, prevents rotation or twisting of the post 102 about its longitudinal axis. The post 102 is raised by mechanism to be described to carry the work first into operative relation to the lower cutter and then into operative relation to the upper cutter. The path of upwardmovement of the work relatively to the cutters is determined partly by a templet 116 secured to the frame by screws 118 which pass through vertical slots in the templet. When the screws 118 are loosened the. templet may be adjusted up and down by a screw 122 threaded into. it

and held from longitudinal movement by collars engaging above and below the arm 112. Co-operating with the contoured edge having a collar 130 engaging a recess in the slide (Fig. 2).

W The post 102, and hence the shoe, is

raised slowly and positively by mechanism to be described. Obviously, the lower convexity 131 of the templet will act upon the roll 1 24: to determine the path of in and out movement of the shoe relatively to the lower cutter 16, the out upon the heel starting upon the upper side of the heel with the shoe close'to the cutter, the shoe being moved away from the cutter until the center of the heel breast is reached, and then the shoe moving toward the cutter again until the cut is finished on the lower side of the heel. The breasting operation, therefore, takes place progressively from side to side of the heel, the longitudinal curvature of the heel breast being determined by the shape of the end and right-hand side ofthe blades of the cutter 16 which are suitably During this movement the shoe is held. as shown in. Fig. 5) with the face of its shank in engagement with the guard 52 as is permitted by a lateral play of the post 102 in the slot 111 of the arm 112, the lower end of the post pivoting on the stem 117. The guard 52- acts as a guide, cam or templetto determine the position of the shoe leng h:

wise of the cutter shaft and its edge where it engages the shoe shank is so contoured relatively to the contour of the .templet 11 6 that, as the shoe is being guided out and in by the templet- 116, it will at the same time be guided to and fro longitudinally of the cutter shaft-o1 transversely of the plane of movement of the cutter by the guide 52, and the cutter will be caused :to trim the base portion of the heel to the transverse curvature of the shank. During this operation guiding o f the shoe is effected in such man-- ner that the effective point of contact of thecutter and shoe is moved along :the cutter periphery as said :point of contact moves from one side of the shoe to the other.

Since :the "formed cutting edge of the cut mally would be rectilinear, :to compound with such relative niovement (which effects a relative movement of approachand separation between the cutter and the central point 'of the j unction of :the shank and heel breast) a component of successive relative separation and approachso asto cause said central -point and cutter -to move relatively in a curve correspondingly to the desired convex curveat the junction of the shank and breast. Should the templet 1116 ibe made straight so as to effect the cutting ofa straight crossgroove'in -the heel breast, the guide would be designed to-effect the proper movement of the shoe so that the cutter :would still trim ;the base portion-of the 'heel breast to'the curve of the shank where the surface of the heel joins the surface'of the shank.

As theshoe continues'toiriscythezroll 12a will engage the upper convexity 133 of the templet 11G=which moves the shoe outwardly to prevent engagement of the heel with the cutter 18 until the center of the heel breast is oppositethe center-50f thecutter, whereupon :the shoe stops. The .roll 124: is noW-beyondthe'top of thetemplet and movementofthe shoetoward the cutter is permitted. Duringthe upward movement oftheshoe, a: pinllie, having aconic-al. end.

portion and carried by a portion of the.

member 10.0.extending above the shoe, has cnteredaslot 136 (Fig. in a part 138 bolted to the top of the machine frame. As the conical end of the pin l3atcnters the slot it centers the ,shoe laterally relatively to the slot and the slot guidest-he shoe in its movement toward the cutter 18, the depth of out being determined by a screw 140 with which the rpm 134 contacts .when

the cut is completed. This cut is a concavity or scallop limited to the portion of the breast adjacent to the top :lift and is, of course, the shape of the cutter 18 and of such a depth asto extend substantially from corner to corner of the ibreast edge of the stop lift. During thiscutting operation the shoe and cutter are in the relation shown in F ig. 6. il heplate 52 is preferably extended upwardly and shaped so as to constitute a ,guard for the cutter 18 .as Well as forthe cutter 16. The plate 52 is hinged to the frame by a pintle rod 1 1a F-ig. 2) so-that it may be swung outwardly like a door for. examination vor change of thecutters 16, 18. The Xplateais held, in closed position 1by a deaf spring 116 pushed underthe pintle irod andbearing at one end against the iframe andatthe other end against the-plate. The location of the shoe engaging edge of the plate '52 irelatively :to the cutter is adjustably determined by a screw :14? (Fig. 1') threaded through .the frame and [engaging an upwardly extending lug "149 on the plate'52.

It iisidesirableto-provide a guard to cover the front of the upper cutter When not in use and to move the guard away from the cutter when the work approaches .it. For this purpose a guard 1&8 having a curved fl ange extending across the :front face. of! the cutter (Fig. :1) is pivotedat 150-to theiplate 52 and a crank jl52on;tl1e-.pivot ofithe' guard is connected by a :fiexible connection 151, for-example, a. cordatoa part of tllBzlTlflCllillE whichmoves in a direction to apply tension to the cord when :the work approachescthe cutter, .thereby turning the crank fillClilli'ling theguard away :fromzthe front of .the cutter and exposing it --for operation .upon the shoe zh eel. The cord list is connected (as shown ii -Fig. 4r) toatpin -l 5'5.on the lever 119 pivoted at 162 to the frame and carrying at its: outer end the .pivot 110 of the post 102. The movement ofithe clever 119 at the point of attachment of the. cord 15a .is more it'll-2111 that required for the crankto lift theguard. The cordiis therefore, given a certain amount of slack to al.- low the leverito raiserthe work forthe operation of thelower cutter wliiletheguardof the upper cutter remains in guarding posi tion, the slack being taken up ancbthe guard raised astheshoe is raised further zfor the operationiofithe uppericutter. Totake, up the slack of the cord and keep .it'straight at all ,tin esya light coiled spring 161 is provided connected between the pin 'an'd apoint on the cord. such that in the; position of Fi a little or no tension willzbe put upon the cord. The slackof the cord is preferably arranged inside the coiled spring. 1

The tension of the spring is in itself insuflicientto raise the guard and when the slack within the spring is taken up the guard is positively raised by the pull on the cord 154. I

The weight of the post 102 and connected parts is preferably partially counterbale anced by a heavy tension spring 172 con nected between the outer end of the lever 119 and a stationary portion of the machine shown as the member 112.

Means is provided for operating the lever 119 automatically to raise the shoe for the operation of the two cutters in succession and lowering it after the cutting operations, the automatic movements being preferably controlled by movement ofv the work sup port, for example, the post 102, toward and from the machine. The rear end of the lever 119 is. bifurcated to receive one end of a link 178 pivoted to the lever by a in 180. The opposite end of the link 178is on a crank pin 182 of a crank 184 on a shaft 186. Suitable speed reducing gearing is provided between the shaft 4 and the shaft 186. As shown, this comprises a worm 188 on the shaft 4 meshing with a .worm wheel 189 011 a vertical shaft 190 having at its upper end a worm 191 meshing with a worm wheel 192 on the shaft 186. The worm wheel 192, therefore, is continuously. driven at a slow speed when the machine is in operation. Between the worm wheel 192 and the crank 184 clutch mechanism is provided by which the crank 184 is moved 180 and stopped. A clutch disk 194 has a single knockoif projection 196 which co-operates with either of two Jstop arms 198, 200 to throw out the clutch. The stop 198 is pivoted at 202 to a stationary support and the arm 200 is similarly pivoted at 204, the arms being held toward each other and against the disk 194by a spring 206. On each of the stop arms is a projection 208 and between them is a swinging link 210 pivoted at 211 to the frame and arranged when swung to contact with one or the other projection 208 and to push one or the other stop arm out of engagement with the knockof? projection 196 to start the machine. A link 212 connects the link 210 with the post 102. lVhen the post is swung in toward the machine and the link 210 swung against theprojection 208 on the arm 198 that arm is pushed out of engagement with the knockoif projection 196 (as shown .in Fig. 4), allowing the clutch to go in and the crank 184 to revolve and through the link 17 8 to operate the lever v119 to raise the post 102 and the shoe supporting" and positioning When the shoe is completely raised inposition to be moved inwardly of the machine for the operation of the cutter 18 upon the heel, the knock-ofi projection 196 ongagesthe stop on the arn1 .200 'and ver- 1,51assi tical movement of the shoe ceases. After the operation of the cutter 18 the shoe and post 102 are movedoutwardly, the pull on the link 212 moving the arm 200 out of stopping position and allowing the crank 184 to move through another 180 to its original position where it stops with the shoe lowered. I

In the operation of the machine a shoe is grasped by the operator with both hands and positioned with the tread face of the heel against the plate 40 and with the rear. end of the heel adjacent to the top lift abutting against the surface of the member 76. The bottom ofthe forepart of the sole is held against the spindle 42 which has been rotated to bring into position a pair of pins 46, the pins of which are so spaced as to hold the forepart of the shoe against lateral movement. The operator now presses upon the lever 81 with his right hand which still grasps the heel end of the shoe. The shoe is now definitely positioned relatively to the shoe support or carrier ant held in position thereon. Next by pressing upon the shoe the carrier isswung on the form given to the portion of the heel breast which hes transverse to the plane of rota tion of the cutter (Fig. '6). while the longitudinal curvature of the breast is determined by the contoured edge or form of the cutter 16. During this movement the support has been pressed inwardly to maintain the roll 124 in contact with the templet 116 and hasbeen pressed sidewise toward the right to hold the shank. of the shoe sole in contact with the contoured edge of the plate 52. This edge acts as another cam or templet to control movement of the shoe in a direction substantially perpendicular to the shankportion and to the breast face of the heel or lengthwise of the cutteraxis and causes the cutter to follow the transverse contour of the shank and to trim the base portion ofthe'heel inconformity with the curve of the shank. The movement of the shoe past the cutter being gradual and controlled at all times by power, the heel as it cord in and the stud 134 enters the slot 136 which prevents lateral play of the support and guides it for presentation oft the tread portion of the heel breast to the cut-- ter 18 .(Fi'g. The support now stops in its upper position and 1s swung in toward the cutter as far as permitted by "the abut-' ing of another on the support. TVhether the support has to be pushed down or drops by gravity depends upon the tension of the spring 17 2 and both arrangements are contemplated as within the invention. The descent of the support ahead of its] power actuation is, of course, permitted "by theusual one-way ball or roller clutch forming apart,

of the usual clutch of the Horton'ty'pe.
